+## D5-Bau-Nachweis (t_e81aed01): platziert je 1 Natur-Objekt (Fels, Kaktus, Decal)
+## ueber die EDITOR-eigene Aufloesung (GlbMeshStore.mesh_fuer — Registry-glb +
+## Fusspunkt-Normalisierung) auf einer Bodenplatte und rendert ein PNG.
+## Beweist visuell: Fels/Kaktus STEHEN auf dem Boden, das Decal LIEGT FLACH
+## (2 cm Lift gegen Z-Fighting).
